USB host is unable to program flash

Problem environment

Using a custom bootloader, MCU flash storage can be programmed over the USB. This feature could allow a connected host (USB DFU like on Arduino) to reprogram the sendcomm transceiver.

Expected result

The dfu-util(1) or sam-ba(1) applications can be used to load and program a SAMR34 (Cortex-M0+) firmware to the chip's flash storage.

$ sam-ba -h
$ dfu-util -D SendcommLWOTAA-rel.bin

Actual result

There is no possibility of programming the chip's flash storage conveniently using dfu-util(1).

Notice

In the document SAM R34 MLS Getting Started Guide, the section 5.5 Bootloader contains the information Figure 5-8. Bootloader Organization in SAM R34 providing clues how to implement this feature.

Workaround

Use a serial debugger (JTAG/SWD) in the usual manner.

Severity level

This is low priority because no requirements specify the feature.
